Malwarebytes is completely gone. Even Revo has no file info. I tried reinstalling and it failed. I downloaded and installed the newest version of Malwarebytes. It will not install. Message about another application using a resource.
Bit Defender is alive but has been unable to download updates. Turns out for at least March 27. I tried to update it. Nothing.
An issue that may or may not be involved. I installed a new router (Asus AC3100) a few weeks ago. Everything worked fine, and internet access was very fast. Then I could no longer sign on as the administrator. I have tried a number of permutations of a logon to no avail. I have the name and password written down ,and it should not have changed. A previous older router also did this, and it was very slow. I did not associate it with the new router until ti started to get very slow. And I could not log on.
Using the computer, it is very slow to log on to a site or download material.
Last week I used the system to activate a new Motorola phone. It worked.
I have run Farbar and have the files available.
A several weeks ago, my system was trying to encrypt all of my drives. I interrupted it. When I tried to kill the process, it wanted me to enter a password. I was afraid this would allow a possible attacker to do a ransom ware trick. I reformatted all drives, and installed a previous installation from Macrium.
